Don't go crazy on a maniac. This way you'll be the maniac in the game. You can loosen up a bit by raising mid or low pairs an good draws. Just be patient and wait for a good hand and bust him.
Here i would raise the flop and call down. Then i would thuse the check fold on the flop if you don't hit and a check raise if you hit.
